Steam Siege Booster Box
Booster Box of Steam Siege (STS), released August 3, 2016. Market price from TCGplayer, updated daily.
Is the Booster Box worth it?
Opened, the booster box costs you $39.92 a pack, against $32.85 for a single Steam Siege booster pack: 22% more than single packs, so you pay for the extras or the box itself. The 9 hits of Steam Siege (Double Rare and up) are worth $181 together; the five most valuable make up 92% of that, so most boxes miss the cards that carry the value. Buying the single card you want is usually cheaper than opening for it; see the Steam Siege chase cards.
